Hi folks, We have some old DVR running Windows XP Embedded with no Service Pack installed. I know SP1 comes with the Windows Firewall, but I was wondering if there is any other way to block an incoming network connection without using the Windows Firewall? Maybe a trick using the host file? Or, using a light open-source firewall software? I'm open to ideas. Thanks for reading. ...Alex
